8PPM HYDROGEN

Turn water into hydrogen water

Inside every Flask, is a specially designed membrane originally designed by NASA to carefully split water apart — releasing pure hydrogen, the same tiny spark that powers stars and helps your body work at its best.

But doesn’t water already have hydrogen?

Yes, but it’s locked up. Just like we can’t breathe the oxygen in water, our bodies can’t use the hydrogen that’s still bound to it. The ECHO Flask frees that hydrogen, so your cells can actually use its powerful benefits.

Grounded in research and refined through years of innovation

ECHO Water has been the global leader in hydrogen hydration since 2014. We make hydrogen water simple—so you can focus on feeling better every day.

    H2 water has significantly decreased low back pain

    I'm 80 years old. I have had chronic low back pain for several years, caused by arthritis. Three months ago I started drinking 3 or 4 flasks, consistently every day. My back pain is gone. It's unbelievable.
